This is an immersive projection design project about land reclamation in Hong Kong. The project aims to explore the pollution caused by land reclamation in Hong Kong to the ocean. By using a 360-degree camera underwater from the perspective of a fish, it presents a panoramic view. The project intends to focus on the underwater world of fish from such a perspective and also hopes to remind people to pay attention to marine protection issues, and create a better marine environment together.
